This is pretty much the coolest bag I've ever seen. It's big enough to hold everything I need, seems well made and of higher quality than I expected, and the holo effect is just so cool! When indoors or in dimly lit spaces it is like a slate grey color and you can kind of see the rainbow shimmer, and then when the light hits it is when you can see the holographic part best. The two pictures I've attached are without and with flash, respectively. The triangles on the outside are stiff, which holds the bag in kind of a geometric shape when placed down. Overall, super cool purchase and I'll be ordering the wallet to go with!
